Xanthan gum enhanced fire-retardant compositions

Abstract

A fire-retardant composition for application to vegetation, to suppress the spread of wildfires of the type which includes a fire-suppressing salt in a liquid carrier, has a minor amount of xanthan gum incorporated therein to improve the stability, corrosivity or adhesion of the composition.

I claim: 
     
       1. In a fire-retardant composition, specially adapted for aerial application, to suppress the spread of wildfires, said compositions consisting essentially of a fire-suppressing salt selected from the class consisting of ammonium phosphate, ammonium polyphosphate and ammonium sulfate,   a guar gum thickener, and   an aqueous liquid carrier, the improvement for increasing the long-term stability and adhesion characteristics of said compositions, comprising     the addition of xanthan gum, in a minor amount effective to improve said characteristics.
